Title: Improvements in remote control apparatus
IPC: F02M13/08
Filed: 1943-06-28
Abstract: 558,796. Starting and regulating. EXACTOR CONTROL CO., Ltd., and REMINGTON, J. G. June 28, 1943, No. 7186/42. [Class 7 (v)] [Also in Group XXIX] A hydraulic remote control apparatus particularly adapted for the graduated operation of a pair of fuel supply valves, controlling the supplies of alternative fuels, one of which may be for starting, to an internal combustion engine comprises a manually operable control unit A actuated by a handle 16 or pedal 19 and operatively connected by a pipe 1 with a power unit B. The piston rod 2 of the power unit is pivoted at 4 to a floating lever 5 the ends of which are coupled by links 8 to crank arms 12 operating butterfly valves 10. The ends of the lever are equally loaded by springs 14,15 the tension of the spring 15 being always greater than that of the spring 14 so that during the initial movement of the rod 2 the valve D is gradually opened while the valve C remains closed. Continued movement of the rod 2 brings one arm of the lever into engagement with a fixed stop 20 ; this tilts the lever in the reverse direction to close the valve D and open the valve C. This reverse movement may be effected by a second control handle connected by linkage or a Bowden cable with the end of the lever 2 loaded by the spring 15. The links 8 may be coupled to the controls for a second engine, and the movements of the lever 5 may also control the ignition timing. Weights may be used in place of the springs.

When the vibrator cools a partial vacuum exists within the housing.
Patent GB-591015-A (GB)
Title: Improved method of heat treating compressed carbon bodies for electrical and like purposes
IPC: C01B31/00
Filed: 1945-03-22
Abstract: 591,015. Carbonizing processes. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. March 22, 1945, No. 7257. Convention date, July 17, 1941. [Class 55 (i)] Compressed green carbon bodies are carbonised without deformation to produce predetermined physical and electrical properties by flowing a controlled gas atmosphere, substantially free from oxidizing gases, over the bodies while heating at a thermal gradient of from above 5‹F. to 360‹F. per hour or higher to a predetermined heat-treating temperature which is maintained for a period. Carbon plates 24, loosely stacked to ensure penetration of the controlled atmosphere, are placed within a furnace 10 containing resistance heating elements 16 and having an inlet 18 and an outlet 20 for gases which may comprise hydrogen, nitrogen, carbon dioxide, carbon monoxide or hydrocarbons the combination used depending upon the properties desired in the finished product. With the gas or gases flowing, heating proceeds at a rate of 5‹F. to 360‹F. per hour, or higher, to a temperature of 1800‹F. to 2200‹F. depending upon the subsequent operation to which the plate will be subjected. Thus, for plates to be subsequently graphitized at 3000‹F. to 5500‹F, 1800‹F. is suitable, but in cases in which no further heat treatment will be given baking at 2200‹F. is desirable. Porous plates are produced by baking compressed green carbon plates in which a readily volatilized material, e.g., urea has been incorporated in the green carbon flour before compression, at a thermal rate of 5‹F. to 25‹F. per hour up to a temperature at which the volatile material has escaped from the carbon bodies, and then heating at a rate up to 360‹F. per hour, or higher, to the predetermined carbonization temperature. The amount of sulphur in sulphide form present in the plates is greatly reduced by the treatment. A bell-type furnace having an atmospheric seal and gas distributing hood and a continuous type furnace in which the carbon plates move in countercurrent to the gas are described.

Title: Pile compressor
IPC: B65H31/26
Filed: 1962-02-26
Abstract: 933,257. Packaging-machines. TIME Inc. Feb. 26, 1962 [Feb. 27, 1961], No. 7374/62. Class 94(1). Piles of newsprint 11 are carried on intermittently moving conveyers 12, 13 to a position below a compressing unit 20 carried on slides 21, vertically reciprocated on rods 24 by means of a pneumatic cylinder 27 under electrical control, the unit 20 having a pivoted plate 42, for compressing the curled edge of the piles, which operates after a pressure plate 40 for compressing the flat portion of the piles. A time switch 35, which may be controlled by other parts of a handling and conveying system, actuates a solenoid 64 to cause a pressure channel device 62 to operate the piston of a rack and pinion driving the conveyers. A ratchet in the drive to the conveyers causes them to be stationary during compression of the piles. A switch 67 operated by a member on the rack 65 actuates a similar circuit to lower the piston of cylinder 27. As the plate 40 compresses the flat portion of the pile, a pre-determined pressure in the cylinder 27 actuates a switch 45 which, by means of a further circuit, lowers the piston of a cylinder 48 in the unit 20, thereby forcing down the pivoted plate 42 on the curled edge of the pile. De-actuation of switch 67 reverses the cycle.

Title: Improvements relating to electric discharge devices
IPC: H01J17/58
Filed: 1935-03-11
Abstract: 432,177. Thermionic valves. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. March 11, 1935, No. 7548. Convention date, March 15, 1934. [Class 39 (i)] [See also Group XI] In a gas-filled rectifier the thermionic cathode 4 is surrounded by three concentric heat shields 9, 10, 11, provided with a number of registering orifices 18, a further shield 21 being placed outside the heat shields to protect the corrugated anodes 5 from sputtering from the oxide-coated cathode ; the holes 22 in the shield 21 are staggered in relation to the holes 18. The shields 9, 10, 11 are spaced apart by indentations and are closed at their ends by plates 12; the shields 9, 10 are approximately of the same length as the cathode but the shield 11 extends the length of the anodes. A partition 17 with inturned edges 19 extends beyond the anodes and divides the envelope into two chambers. The envelope may be of glass or of metal; in the latter case the envelope partition and shields may be all of cathode or other potential; the heat shields are carried by the partition. The partition is held in position by wedges and rods bearing on the glass envelope. More than two chambers may be formed by the partition when the rectifier is used with polyphase currents. The anodes are hung from U-shaped frame members 23 which are also connected to the partition 17 with the interpositioning of lava blocks 25. The cathode may be of the multi-plate construction described in Specification 386,376; it is supported by the partition 17. When a glass envelope is used the electrode structure is supported at the foot from four metal caps 27 sealed to glass cylinders 28 by means of butt joints; the metal cap and glass cylinder are of the composition described in Specification 361 /35. The cathode leads are taken to the caps 27. When a metal envelope is used the partition is supported directly therefrom instead of from the caps 27. In this construction the glass cylinders 28 are welded to metal projections on the envelope. The seal between the glass cylinders 28 and the metal parts is formed by heating by high frequency induction the metal while in contact with the glass, thus the consequent heating of the glass causing it to " wet " and adhere to the metal. The lead 30 has a sheath 29 which is welded to the metal cap 27 to which the support or lead 26 for the electrodes is also welded. A getter capsule is carried by one frame member. The filling consists of argon or neon at 100 microns or mercury at 50 microns when the temperature of the condensate is between 60 and 80 C.

Abstract: 784,674. Tyre repair plugs. SALESCASTER, Inc. March 12, 1956 [April 29, 1955], No. 7581/56. Class 144 (1). A tyre repair plug comprises a rubber cylinder having a pointed end 4 and a blind axial bore which terminates at the pointed end 4 in a reduced diameter portion, thereby providing a shoulder on which inserting pressure is applied by a corresponding shoulder on the operative end 8 of an inserting tool 7, the tool having a reduced diameter tip 9 to enter the reduced diameter portion of the bore in, and thereby support, the pointed end 4 on insertion in a puncture. The plug shoulder prevents rupture of the pointed end by the inserting tool end during insertion in a puncture. To reinforce the pressure-receiving shoulder in the bore, a flat washer 5 may be moulded in the plug to overlie the shoulder. Alternatively the reduced diameter end of the bore may have a frusto-conical lead thereto reinforced by a coned washer 13, Fig. 7. Fig. 5 shows the reduced portion of the bore as conical in form, reinforced by a conical insert 10, which may have an open apex and may be stamped or cast, the end edge of which forms the shoulder. To effect better sealing with the puncture, the plug may have external circumferential ribs 6, Fig. 3, or barbs, Fig. 5, or corrugations, Fig. 7. Further, as shown in Figs. 1 and 3, a frusto-conical fin 6a may be provided near the pointed end to abut the inner surface of the tyre on withdrawal of the tool.

Filed: 1970-02-17
Abstract: 1285656 Program - controlled exchanges TELEFONAKTIEBOLAGET L M ERICSSON 17 Feb 1970 [18 Feb 1969] 7642/70 Heading H4K [Also in Division G4] In a program-controlled exchange where it is necessary to delay the use of an address by a number of clock pulse periods a buffer store comprised of sections B0 to B7 is employed with a counter I driven from a clock CL in such manner that the store section marked by the counter is reset by a clock pulse over gates AN0 to AN7 before the counter is advanced to the next store section, each section marked by the counter being available between clock pulses to receive an address from a store IR by way of the gates A10 to A17, each address when registered in a store section causing the counter I to advance to make the next section available for another address should this be presented, a counter U driven by the clock CL and initially set to run a number of steps N behind the counter I successively enabling read-out gates A0 to A7 for each section, the counter U being stepped by each address read out to effect readout of the next section and so on should succeeding sections register addresses, the arrangement being such that an address is read out after a number of clock pulses related to the number of steps N separating the initial states of counters I and U. Should the counters I and U, for instance, be initially set such that I indicates section B5 while U indicates section B2 following clock pulse t0, all those addresses registered in sequential sections between clock pulses t0 and t1 are read out sequentially following the appearance of clock pulse t3; those registered between t1 and t2 being read out following t4, and so on. The buffer store becomes full when the counter I is advanced by so many address registrations that it is cycled round to the same setting as counter U, coincidence between the couners being employable to prevent further registration of addresses until reading out has cleared space. The exchange processor may be served by a number of such buffer stores each providing a particular delay.

As described the machine includes a pair of guide rods 18, 20 on which is fixed a central last support 22 including a toe rest 24 and last pin 26. Carriers 28 are slidably mounted on the guide rods 18, 20 and are movable towards and away from each other by air motor 38 between outer positions determined by stop rings 30 and inner positions determined by adjustable stop bolts 34. The carriers 28 are locked in their inner positions by pawls 48 engaging ratchet teeth 44 (Fig. 4), the pawls 48 being retracted by cams 58 when the motor 38 urges the carriers 28 outwardly. A base 68 is mounted on each carrier 28, by means of links 70, 72, the height of each base 68 being adjusted by bolts 78, 82. Each base 68 carries a plurality of lasting tools 124, each of which includes a bracket 88 adjustable widthwise of the shoe on base 68 by means of screw 86. Each tool 124 also includes a bracket 92 slidable on base 68, a block 114 slidable heightwise on bracket 92, a lasting strap 134, an inner presser strap 132 and an outer presser strap 130. The piston rod 100 of air motor 98 is connected by levers 102 and 110 and links 135, 142, 146 to the block 114 and straps 130, 132 and the piston rod 158 of air motor 150 is connected by ball joint 156 to the top end 134b of lasting strap 134. In operation a last carrying an upper (which has previously been toe and heel lasted) is placed on the last support 22 and the operator actuates motor 38 to move the carriers 28 inwardly to positions determined by stops 34 where the lasting tools 124 are adjacent the upper. Motors 98 are then actuated which causes each block 114 to clamp the bottom end of the straps against the top line of the upper and then causes the inner and outer presser straps 130, 132 to press against the upper. Each air motor 150 is then operated under low pressure so that the lasting straps 124 apply a back-up pressure to the lasting margin while thermoplastic cement is applied to the angle between the insole and the lasting margin. Each motor 150 is then operated under high pressure which causes each lasting strap 134 to stretch the upper and wipe it over the insole. After a predetermined time delay the various parts then return to their initial positions.
